Jianjing (GB21) — anatomical left
Shoulder well — kneading press
Jianjing is the Gallbladder-channel shoulder-well point approached in tuina with broad, moderate kneading rather than a sharp poke. The left shoulder coordinate is an editorial front projection, and force should remain gentle in self-care because the region contains vulnerable structures.
Point 6 of 16 in Anmo-Tuina Acupressure — self-massage circuit
